Filter by:The purpose of this study is to evaluate outcomes of subjects undergoing myopic surgery using the WaveLight® Refractive Suite (Excimer EX500 and Femtosecond FS200 lasers).
The purpose of this study is to evaluate the accuracy of the WaveLight FS200 femtosecond laser, as assessed by 1 day and 1 month post-operative OCT anterior segment corneal measurements compared to pre-operative flap thickness target.
The purpose of this study is to compare the subjective performance of two daily disposable contact lenses with respect to comfort and handling.
The purpose of this study is demonstrate substantial equivalence of an investigational contact lens disinfecting solution to a commercially available contact lens solution in gas permeable lens wearers.
The purpose of this study is demonstrate substantial equivalence of an investigational contact lens disinfecting solution to a commercially available contact lens solution in silicone hydrogel and soft contact lens wearers.
The purpose of this study is to compare the subjective performance of two daily disposable contact lenses with respect to comfort and handling.
Limbal ring contact lenses enhance the look of the eye by adding pigmentation in a ring pattern to the contact lens. The purpose of this investigation is to determine if corneal staining increase is dependent upon the lens pigment location.
The objective of this study is to compare the ease of removing two daily disposable soft contact lenses off the eye.
The purpose of this study is to compare the amount of coma as measured by aberrometry induced by two silicone hydrogel toric lenses in astigmatic participants.
The purpose of this study was to compare three CE-marked daily disposable contact lenses for tear film stability as measured by pre-lens non-invasive keratograph break up time (PL NIK-BUT). Secondarily, contact lens surface wettability was assessed.
